I've got a big Problem with Soft Edges.
I have an seperated Object, some parts have Soft Edges, and others have Hard Edges.
When I combine the Objects, the Soft Edges are still soft, but when I combine this Object with another Object, all the Soft Edges get lost.
How i'm able to fix this Problem?

EDIT: Now I've only opened my saved Project from Yesterday, and the Edges of this Object are all harden again -.-

I wan't to combine it, because this one Object ist made up of 100 Objects or more, and at the end, I have to duplicate the Object 40 times.
The Problem is, when I go through soften edges at the end, I have to do it 40 times.
And now I saved the Project with soft edges, opened it the next day, and the soft edges got lost.

could you post your scene file please? I will try and take a look at the weekend.

What I probably have done though, would have been to model all parts to the same level of detail (if it's going to be combined as the same object in the end) so only one normal angle was required per-object. Just some additional edge loops or bevels on the sharp parts,

Now I realised that the Problem isn't combining the Object.
The Problem is, if I close the Project and open it again, all soft edges of this object get lost.
It makes no sense if it's one combined object, or many parented objects.
I think, nobody here knows how to fix the Problem
